    A physical screen, and its associated paraphernalia.

    Define a screen with a given set of :class:`Bar`\s of a specific geometry. Also,
    ``x``, ``y``, ``width``, and ``height`` aren't specified usually unless you are
    using 'fake screens'.

    The ``background`` parameter, if given, should be a valid single colour. This will
    paint a solid background colour to the screen. Note, the setting is ignored if
    ``wallpaper`` is also set (see below).

    The ``wallpaper`` parameter, if given, should be a path to an image file. How this
    image is painted to the screen is specified by the ``wallpaper_mode`` parameter. By
    default, the image will be placed at the screens origin and retain its own
    dimensions. If the mode is ``"fill"``, the image will be centred on the screen and
    resized to fill it. If the mode is ``"stretch"``, the image is stretched to fit all
    of it into the screen. If the mode is ``"center"``, the image is centered
    on the screen. The ``"background"`` painting is done before the image is
    drawn, so you can set the background color for an image by setting
    background here.

    The ``x11_drag_polling_rate`` parameter specifies the rate for drag events in the X11 backend. By default this is set to None, indicating no limit. Because in the X11 backend we already handle motion notify events later, the performance should already be okay. However, to limit these events further you can use this variable and e.g. set it to your monitor refresh rate. 60 would mean that we handle a drag event 60 times per second.

    These groups can spawn apps, only allow certain Matched windows to be on them, hide

    Parameters
    ==========
    name:
        The name of this group.
    matches:
        List of :class:`Match` objects whose matched windows will be assigned to this
        group.
    exclusive:
        When other apps are started in this group, should we allow them here or not?
    spawn:
        This will be executed (via ``qtile.spawn()``) when the group is created. You can pass either a
        program name or a list of programs to ``exec()``.
    layout:
        The name of default layout for this group (e.g. ``"max"``). This is the name
        specified for a particular layout in ``config.py`` or if not defined it defaults
        in general to the class name in all lower case.
    layouts:
        The group layouts list overriding global layouts. Use this to define a separate
        list of layouts for this particular group.
    persist:
        Should this group stay alive when it has no member windows?
    init:
        Should this group be alive when Qtile starts?
    layout_opts:
        Options to pass to a layout.
    screen_affinity:
        Make a dynamic group prefer to start on a specific screen.
    position:
        The position of this group.
    label:
        The display name of the group. Use this to define a display name other than name
        of the group. If set to ``None``, the display name is set to the name.

    Window properties to compare (match) with a window.

    wm_instance_class, net_wm_pid, or wid. Additionally, a function may be
    passed, which takes in the :class:`~libqtile.base.Window` to be compared

    For some properties, :class:`Match` supports both regular expression objects (i.e.
    the result of ``re.compile()``) or strings (match as an exact string). If a
    window matches all specified values, it is considered a match.
